QuestionnaireSet up the ballot as an Affective questionnaire using Hedonic attributes.
Affective questionnaire will allow for more flexible Incomplete Block Experimental Design and Experimental Plan Rotations.

Create an Hedonic attribute type with two choices and label the choices them with the following special TAGs.

select the choice return value to be = 1
select the choice return value to be = 2
select the choice return value to be = 3

The above example will present two choices with the blinding codes for the two samples in randomized order perfectly matching the Rotation Plan in the Test Definition.
Example: Which Sample do you prefer OVERALL?
( ) 135 ( ) 246

Note: The "Attribute Seen With:" option should be set to "Relative Sample -- Last Sample", so that this question is only seen once at the end of the ballot.
Note: Other handy TAGS are available as with all questions types in your SIMS sensory panel software. See the [Notes] buttons.
Note: We have sucessfully tested this method with bigger BIB designs, such as 5C3, 8C4, etc., add some hedonic choices, see same reports.

* See example Print screens shown below for Questionnaire Setup

Experimental Design and PlanSet up your Experimental Design specifying the true absolute number of samples, which is 3 or more for incomplete blocks of PC tests.
Select an Experimental Plan, such as Combination 3 choose 2, or create your own. Number of samples presented is always 2 for PC.
The Design can be either a Balanced Incomplete Block (BIB) or an Unbalanced Incomplete Block (UBIB).
In a BIB Design, there are m = t(t-1)/2 possible pairs, such as for a 3C2 test there are 3 possible pairs, 4C2 6 pairs, etc.
In a BIB Design, to be completely balanced, all pairs must be seen equal number of times. And to eliminate order effect, also present each pair in reserve (m*2)
You may need to create balanced SIMS Experimental Plan, example for 4C2, 12 pairs, 12 34 13 24 14 23 21 43 31 42 41 32.
Create your Test Definition and review your Rotation Plan report in SIMS for accuracy. As always, "Test Your Test".

Reporting and DataThis is an advanced type of question and setup, some attention to details is required for data interpretation.

The raw panelist data saved is the actual 'return values', just like every hedonic question type in SIMS, therefore the raw data return values are *not* the Sample #s, they are positional orders.

• SIMS Raw Data Export Report, by default, the columns for these hedonic questions will display the actual 'return values', not the sample selected.

Recommended: Your SIMS Raw Data Export Report can optionally swap in the blinding-code associated with each panelist response, this may only be beneficial for interpretation if your experimental design selected the option for the Same Blinding Codes for all panelists. See the report's Column Options tab to set this.
Alternative: The raw data can be interpreted by reviewing the actual return values from each of your panelists while also reviewing which sample set pair the panelist was presented with from the Test Definition Rotation plan.

• SIMS Data Frequency Reports will add additional report lines interpreting the data when these Special Hedonic Sample Choice Tags in Use is detected.
